Pros and cons
Duden Learnattack
Pros
- Leads the free trial length ranking at 1 of 9, giving families more time to judge the app than most rivals allow.
- A free tier means 40,000 courses can be browsed before a plan is chosen.
- Subscription price ranks 4 of 28, so a renewal sits near the cheap end of the field.
Cons
- The catalogue is in German only, so a child studying another language at school gets nothing from it.
- It serves a single market, DE, so the pricing and the curriculum are built for German schools rather than a wider market.
- There is no live tutor in the package: the lesson format is app, so a family wanting spoken help has to look elsewhere.
The Princeton Review
Pros
- A money back guarantee on eligible test prep programs, with a 60 day window and a free repeat of the program for US and Canadian students.
- Breadth under one roof: sat, act and gre all sit within the same provider, spanning school and professional exams.
- Study depth of 3,700 practice questions and 9 full length tests, with live classes and 12 months of access.
Cons
- Entry price of $299 sits well above Testprep Training at $12.99 and Zebra Education at $49.
- There is no free tier, so the 14 day free trial and the free trial lesson are the whole no-cost taste.
- Offline download is not offered, so every practice session needs a live connection.
Who each suits
Duden Learnattack
Who it suits
- German families with school age children who want more practice in math, english and science without booking a tutor.
- Parents who want a long window before paying, since the free trial runs 30 days and the refund promise matches it.
- Learners who prefer short self paced sessions over scheduled lessons, since the lesson format is app.
Who should look elsewhere
- Parents looking for English language reading material: the catalogue is in German alone, so Readability is the alternative to weigh for English practice.
- Budgets that want the lowest listed subscription: Starfall's is $5.99 and Readability's is $19.99, so compare both against the €6.63 rate here before deciding.
- Families who want live teaching: the lesson format here is app, and Schülerhilfe is the listed alternative to check when the delivery model is the deciding factor.
The Princeton Review
Who it suits
- Students in US and CA who want live classes and one provider across sat, act and gre.
- Learners who would rather have money back protection than a bare course: the guarantee is money back and runs 60 days on eligible programs.
- Families who need tutoring alongside exam prep, with 3,000 screened tutors, background checks and a free trial lesson.
Who should look elsewhere
- Budget shoppers, who would start at $12.99 with Testprep Training instead of $299 here.
- Students who need downloadable study material, since offline download is not offered; Zebra Education starts at $49 if entry cost matters more.
- IELTS candidates, who may prefer the specialist route E2Language covers from $69.

Questions about each
Duden Learnattack
How much does Duden Learnattack cost?+
Entry pricing starts at €6.63 and the monthly plan is €6.63. Across the plans the subscription runs €6.63 to €19.97, so the price at renewal sits in the same band as the price met at signup rather than jumping to a different tier. Prices are in euro and quoted for the German market.
Is there a free trial or a free version?+
A free tier is available, so the courses can be sampled before any payment, and the free trial runs 30 days, the longest trial in the ranking. The trial length and the refund window are the same, so an undecided family can start a plan and still walk away from the opening period without a loss.
The Princeton Review
How much does The Princeton Review cost?+
The SAT Self-Paced course starts at $299, and the combined SAT and ACT Self-Paced course is priced above that as a package. Tutoring is separate: $39.99 covers a month inside a subscription range of $39.99 to $179.99, and individual lessons are priced at $29. The course price is the entry payment, while recurring spend comes from the tutoring subscription.
Is there a free trial or a free tier?+
There is a free trial running 14 days, and there is no free tier of study material sitting underneath it. For tutoring, a free trial lesson gives a session at no charge before any commitment. Together those two make up the entire no-cost entry route into the brand.
